range:

Explanation:

Step1: Identify domain

The domain is the set of all possible x - values. Looking at the graph, the x - values extend from negative infinity to positive infinity.
$(-\infty,\infty)$

Step2: Identify range

The range is the set of all possible y - values. From the graph, the y - values also extend from negative infinity to positive infinity.
$(-\infty,\infty)$

Answer:

Domain: $(-\infty,\infty)$
Range: $(-\infty,\infty)$
